I guess you'd just have to say, " It's one of those physics things"!Įtymology: German, literally, decelerated radiation However the electrons energy is influenced, after the change in direction, due to the influencing nuclide, seems unrelated to the actual Bremsstrahlung event, even if it happens simultaniously. Mass is energy and energy is mass, they convert directly to each other. Based on this immediate radical change in electron direction and the secondary photon produced, it all falls under the conservation of mass/energy. The Bremsstrahlung photon is produced at the time of the vector change, not after the vector change. At the time of this event, the electron does in fact decrease in its energy state, or in layman terms," Brakes "! This can be measured by comparing the resulting electron energy and the secondary photon produced.

Therefore someone has to make a stand and say it doesn't!Īs I was taught, Brensstrahlung Radiation is emited when a high energy electron is deflected off of its mean free path, due to the influence of a high mass nuclide. I guess it's just the nuclear mantality! Bremsstrahlung, in German, translates to," Braking Radiation". My opinion, for what it is worth, is that the person who wrote that NU test question, with the answer as Accelerating, is WRONG! I believe that person compiled a number of events, beyond the Bremsstrahlung theory, to justify an ambiguous answer. Hey, it's all in the wording! Is that braking, as in slow down, or brake left/right? Once again my allergies have increased due to the amount of dust I have to wipe from these antiques. hmmm :-?Ĭool thread, nowz eye gotz sumtin ta think bout twoday. look at it as radition that is breaking off from the electron as it undergoes velocity changes. shapiro uses would work for both acceleration and deceleration. however, the "breaking" radiation terminology mr. i was always under the impression that bremsstrahlung was "braking" radiation. The photons are generally referred to as Bremsstrahlung (breaking radiation), because the electrons lose energy and slow down in the process of emitting the radiation." Such acceleration results in the emission of photons of x-radiations. The most important mechanism, from the point of view of the use of x-rays in radiography, is through a violent acceleration of the electron, resulting in the sharp deflection, as it interacts with the electrical field around the nucleus. Electrons accelerated (shown here as a change of direction) near the highly charged nucleus of a heavy element may lose all or most of their energy through the emission of photons (called Bremsstrahlung, meaning “breaking radiation”) Bremsstrahlung production by acceleration of bombarding electrons.
